The primary objectY of the inventionis to pro- .vide a device which is adapted for attachment to the filler tube of the engine whereby the desired quantity of oil may .be substantially instantaneously dumped there-into for flowing as it may into the crank case upon closing the cover of the device.

Another objectof the invention is to provide a device of this kind onthe order of acontainer adapted to have itsdischarge. end connected to the iiller tube, which device includes a valved bottom that. automatically closes uponl opening of the cover for the introduction of the oil and automatically opens upon closing of the cover so that the oil may iiow from the container down through the ller tube into the crank case.

A further object of the invention is to providev a device of this kind which may be readily applied to engines already in service simply by substituting the same for the cap of the filler tube.

Still a further object of theinvention is to yprovide a device .of this kind which maybe produced at zin-extremely low cost and-has'its parts soarranged that the device cannot readily get outof order. Y

These objects of the invention as well as others, together with the many advantages thereof will more fully appear as I proceedrwith my speciiication. i

In general my invention contemplates the provision of a casing, thebottom of which is formed with an angularlydisposed funnel like neck for insertion in the top end of the ller tube of the engine. yIn the bottom` end of the Vcasing is a transverse wall having `an axially disposed hole which is adaptedto be opened and closed bya spring pressed valve stern. The top of the casing i is provided with a hinged cover which when closed depresses the valve stern .tol open said hole so that oil may flow from the casing into When the cover is open for filling closes said hole;

Referring now in detail to that embodiment of the invention illustratedin the drawing, 1

indicates as a whole ari-upright tubular casing having afunnel like bottom 2 which includes an f In the top end of said casing is atransverse crossbar, l having one opening therein arranged axially of the casing. One end .7a of said cross bar is bent upwardly along the interior surface. of the casing to be secured in place thereto by a rivet 9 having a rounded head 10 on the outside oi the casing. The other end 'lb` of the cross bar is also bent upwardly along the interior surface v of the casing to be secured in place by a pair of rivets 11.l Said rivets are also employed to secure a pair of vlaterally spaced ears 12 on theoutside of the casing at the top thereof in line with said bar.1

13 indicates an axially disposed valve stem that has sliding bearing near one end in the opening 8 of the cross bar 7 and has sliding bearing near its other end in a yoke 14 that bridges the holes 6 in the bottom wall 5 of the casing. This yoke is engaged upon a flanged spring seat 15 secured to said bottom wall about the hole 6. On the bottom end 'of the valve stem, below the bottom wall 5 is secured a disc valve 16, in any suitable man-- ner. About midway between the ends of said valve stem-there is .mounted a cupped washer 17 that engages with a cross pin 18 in said stem. A helical expansion spring 19 surrounds that portion of the stem between the washer 17V and Y anged seat 15. and normally acts to urge said stem upwardly to hold the disc valve in a position closing the hole 6 from below.

20 indicates the cover for the open top end of the casing l which cover is provided at one side with a boss 2l adapted to t between the ears l2 before mentioned and to be hinged thereto by the pintle 22. 'Diametrically opposite said boss on the inside of the cover is secured a spring nger 23 having a bent end 24 and adjacent the same is a recess 25.

Preferably but not necessarily so, I provide a bracket 26 that surrounds the casing about midway of its ends and this `bracket is clamped thereto by the draw bolt 27. Said bracket terminates in laterally disposed arms `28 for attachment to any convenient place on the engine.

Assume now that the device is secured in operative relation upon an engine with its discharge neck 3 insertedin the top end of the iiller tube 4 of said engine and it is desired to supply anfaddi- Ational-quantityof oil tothe engine. Such quantities are usually quarts and' therefore I make the device of a capacity somewhat greaterthan aqua-rt, say about one and one-tenth quarts.

The cover 20 is then swunginto open position after releasing the finger 23 from the rivet head 1G. In this opening of the cover which is swung about the pintle 227 it moves away from the top end of the stem 13 when the spring 19 will move said stem upwardly until the valve disc 16 'engages the bottom wall 5 of the casing to close the hole `6 therein.

A quart of oil may `then be poured from any suitable wide mouth container into vthe casing from.l its open top end. As the said open top end is of substantial diameter, it is apparent that this may be quickly done as there is no waiting for yit to flow from a spout of relatively small cross `sectional diameter. This will fill thecasing to althe contents of .the casing drains through the same linto thel bottom 2 and out through the neck 3 thereof into `the V4filler .tube 4 andthence into the engine crank case to which it is connected.

Thus it is not necessary to wait for the oil `to enter the crank case. After the casing has been charged and the cover is closed, the vehicle may at once be put under way. Thus the usual time lost at service stations waiting for the oil to `flow into the crank case is saved.

It is pointed out that the cover is provided with a rim flange which when the cover is closed overhangs and is slightly spaced from the top edge of the casing to permit air to enter the casing as the oil iiows therefrom. Again this construction provides that breather air required inthe crank case. i i

The device described is simple in construction and positive in operation and there is nothing to get out of order. The casing provides a substantially Wide mouth lfor pouring oil thereinto so that this can be quickly done Without Waste due to spillage.

While inv describing the invention, I have referred in detail to the form, arrangement and construction of the various parts thereof, the

`end and a valve associated with said discharge end and movablelongitudinally of the casing to close and open said discharge end upon manipulationofthe cover to open and close said inlet end.
